Yesterday i buy it from the store and start Playbeat 3. So there cames up the window to activate it. I put the licence code in and it shows that the activation was successful. So now when i start Playbeat 3 ist shows at start that it is running in Trial-mode.
Please make sure that you have uninstalled the trial version.
Kindly check your VST, VST3, AU & AAX folders too.
